Patented'sept. 7, 1915.

Application filed November 9, 1912, Serial No. 739,399 Renewed April 6,1915; Serial No. 19,567.

To all whom it may concern Be it known that I, WLLLLAM- T. S. PATE,

a citizen of the United States, and a resident of Bloomington, in thecounty of Monroe and State of Indiana, have invented certain new anduseful Improvements 1n Scrapers for Vehicle-lVheels, of which thefollowing is a specification.

My invention relates to scrapers for vehicle wheels and while admittingof general application is of special adaptability for use upon wagonwheels for the purpose of cleaning mud from the wheels, the actionvbeing practically automatic.

My invention comprehends a number of scraper members having bladesdisposed in different positions relatively to different portions of thewheels, some of these blades being directly under control of theoperator for the purpose of throwing them into and out of action. 1

My invention further relates to'means whereby the scraper mechanism maybe readily dismantled in order toallow the wagon bed to be tilted forthe purpose of dumping a load.

My invention also contemplates a number of improvements in scrapermechanism generally for the purpose of increasing the eflicienoy of thesame.

Reference is made to the accompanying drawings forming a part of thisspecification and in which like letters indicate like parts. a

Figure 1 is a plan view partly broken away showinga wagon equipped withmy improved scraper mechanism; Fig. 2 is a vertical section on the line22 of Fig.1

looking in the direction of the arrow; Fig. 3 is a detail showing one ofthe scrapers used in connection with one of the a rear wheels of thewagon; Fig. 1 is a detail show ing in perspective one of the scrapersassociated with the frontwheels but removed therefrom; Fig. 5 is adetail showing in section on the line 5-5 of Fig. 6 a portion of themeans for dismantling the scraper mechanism; Fig. 6 is a fragmentaryside elevation of the mechanism shown in Fig. 5; F ig. 7 is a detailshowing one of the scraper blades and a portion of the wheel to bescraped by it; and, Fig. 8 is a detail showing in section how thescraper mechanism is supported partially by aid of the spindles of therear axle.

The wagon tongue 7 is shown at 9, the front axle at 10, and the frontwheels at 11. The rear axleappears at 12 and the rear wheels at '13. Thefront axle beam is shownat 11 and the rear axlebeam'at 15. The fronthounds are'shown at 16 and are secured to the front axle and the'frontaxlebeam 141 in the usual or any desired manner. The front hounds-carrya supporting plate 18. The couplingpole'is shown at 19, and by aid-of acoupling pin 20=-is 1 connected with the'front' axle'16 and front axle"beam 1 1. The rear hounds are shown at 21 and are connected by aid of acoupling pin 22 with the coupling pole 19. The-supporting plate 18carries a ,pairof brackets 23 mounted upon its underside by aid ofbolts17. These brackets serveas bearings. Journaledin them-andextendingthrough them is a rocking shaft-24:. Anarm 25 is connected rigidly withthe rocking shaft 24: and extends downwardly therefrom. A link 26 isbyaid of a pivot pin 27 connected with the lower end ofthearm 251 Thislink 26 is also connected with a flat bar 29 byaid of a bolt 28. Thisbolt allows some-adjustment :of the link -2G-relatively to the bar 29and may be tightened so as to render these two parts rigid relatively toeach other, and to all intents and-purposes cause them to act as asingle bar.- Engaging one side'of the bar 29 is another-bar 30 providedwith a sliding head 31 or eye which partially encircles the bar 29. Thebar 30 is adjustable relatively to thebar 29,-the eye 31- serving tomaintain these bars inproper derside of the rear axle 12 is a plate 38se-.

cured in position by aid of U-shaped brackets 39 carrying nuts 40 attheir lower'ends. These brackets 39 are adjustable relatively to therear axle 12 and may be moved closer together or farther apart asdesired thereby spacing the plates 38 (of which therejare two) at anyrequired distance apart; Disposed adjacent to the plates 38' are twoflat barsl each provided with an eye ll Extending through eacheye 41 isa pivot pin 42 which serves as a bearing and is supported by a pivotframe 42*, the latter being secured rigidly upon the plate 42. There aretwo of the fiat bars 41 and the parts associated with them are of courseduplicated.

Mounted upon the rear axle beam 15 are two strap sections 43 and thesecarry bearing frames 44 similar to the bearing frames 42" abovedescribed. Two strap sections 45, each having-the form of a wide fiatbar, are provided respectively with eyes .46, the latter being adaptedto enter the bearing frames 44. A rod 47, which is of considerablelength, extends through the two bearing frames 44 and through the twoeyes 46 and serves to hold the strap sections 45 in en gagement with thestrap sections 43. WVhen, however, the rod 47 is withdrawn, ashereinafter described, the strap sections 45 are disengaged from thestrap sections 43. The rod 47 isprovided with a head 47" (see Fig. 5) byaid whereof the rod may be withdrawn asindicated by dotted lines in thisfigure. The strap sections 45 are at their rear ends (see Fig. 1)provided with holes 48. Bolts 49 extend through the bearings 37 (seeFig. 2) and through some of these holes, the bearings 37 beingadjustable relatively to the strap sections. of the rocking shaft 36 arearms 50 secured in position by aid of clamps 51. These arms 50 carryscraper blades 52 for engaging the inner annular faces of the rear wheelrims and'also carry scraper blades 53 for engaging the peripheralsurfaces of said rear wheels. A pair of arms 54 are by aid of bolts 54"secured to the strap sections 45 extending directly outward therefrom asmay be understood from Fig. 1'. I These arms are at their outer endsconnected to two other arms 55 which extend forwardly toward the hubs 56of the rear wheels. One of these hubs is shown more particularly in Fig.8. The rear axle is provided ateachof its ends with a spindle of theform shown in Fig. 8, this spindle at its outer end being provided witha thread. Revolubly mounted upon the spindle is a nut 57 which isprovided centrally wit-h a threaded boss 58, this boss extending througha hole in the adjacent end of the arm 55 and being engaged by a tap ornut 59 as indicated in Fig. 8. By loosening the nut 59 the arm 55 may bedisengaged from the threaded boss 58 without disturbing the hub or thewheel 13.

Mounted upon the rocking shaft 24 by aid of clamps 61 are arms 60carrying blades 62, 63 which are disposed adjacent to the front wheels11 and are adapted for keeping the same clear of mud. Arms 64 disposedadjacent to these scraper blades are connected with threaded bosses 65and held in position by nuts 66. These arms are adjustably connectedwith other arms 67 ex- Mounted upon the ends 64, are provided withportions bent slightlyinward toward the adjacent outer facesof the rimsof the wheels 11, 13, such portions thus serving as scraper blades forcleaning the wheels.

A link 69 (see Fig. 2) is pivotally connected with the arm 25 and with alever 70. This lever is journaled upon a support 71, the latter beingsecured upon the Wagon tongue 9 by aid of fastenings 72. The lever 70 isprovided with a portion 74 integral with it and extending forwardly. Atensile spring 7 5 is connected with this forwardly projected portionand with the tongue 9. Another tensile spring 76 extends from the lowerendof the lever 70 to the tongue 9. Normallv the springs 75, 7 6 holdthe lever 70 in the position indicated. Connected with the forwardlyprojecting portion 74 of the lever 7 0 is a link 77. This link is alsoconnected to a hand lever 78 which is journaled at 7 9 upon the wagonbed 81. Mounted upon the wagon bed is a rack 80 having a substantiallyarcuate form and disposed adjacent to the path of travel of the handlever 7 8. This hand lever carries a pawl 83 and a pawl handle 82 foractuating the pawl which is adapted to engage the upper or tooth edge ofthe rack 80 so as to holdthe hand lever 78 in different angularpositions into which it is moved from time to time.

At one side of the vehicle I provide two shields 84, 86 and pivotallymount the same 6 upon the bearing frames 44, 42 Pivotally connected withthe two shields just mentioned is a hand lever 85. The pivotalconnection between this hand lever and the shield 86 is made by aid ofapivot pin 87. The shield. 84 normally covers the head 47 ofthe rod 47,and the shield 86 covers the head of the pivot pin 42,1ocated directlybelow; the rod 47. If, however, the hand lever 85 be'moved bodily to theleft, soas to swing the shields 84, 86 each slightly in a clockwise Idirection according to Fig. 6, the head 47 ofthe rod 47 and the head ofthe pivot pin 42 are thus uncovered and rendered accessible, so thatthey may be readily withdrawn.

The operation of my device is as follows :The parts being arranged andassembled as above described, the wagon is ready to proceed upon itsjourney. Normally, the various movable parts above described occupy therespective positions indicated in Fig. 2. In this event, the severalscraper blades are adapted to strip the mud from the wheels if thecharacter or quantity of the mud requires no special attention. Itsometimes happens, however, that the mud is very tenacious or from someother cause it may be desirable to force the scraper blades into closerengagement with the wheels. The operator thereupon grasps the hand lever78 and the paWl handle 82. By

aid of the pawl handle, he disengages the pawl 83 from the rack 80. Henext draws the hand lever 78 backward, and in so doing rocks the lever70 in a direction which is counter-clockwise according to Fig. 2. Bydoing this, motion is transmitted through the link 69 and bar 29 so thatthe arms 25, 34, are actuated and the rocking shafts 24, 36, slightlyturn. This brings the scraper blades into more favorable position forstripping the mud from the wheels as the latter roll along.

In some instances, it may be desirable to dismantle a part of themechanism asso ciated with the rear wheels, for the purpose, forinstance, of enabling the wagon bed to be tilted in order that the loadcarried by it may be readily dumped to the rear of the wagon. In orderto thus dismantle the scraper mechanism, the hand lever 85 (see Fig. 6)is moved bodily to the left so as to turn the shields 84, 86. Thisuncovers the head 47 of the rod 47 and also the head of the adjacentpivot pin 42. The operator now grasps the head 47 and completelywithdraws the rod 47 He also takes out the adjacent pivot pins 42. Thisdisengages the eyes 46 and 41 The strap sections 45, 41 therefore becomedetached, it being understood, however, that the tap nuts 59 are firstloosened. The scraper mechanism at the rear of the wheels is thuscompletely dismantled. This part of the apparatus is of special servicein instances where it is desirable to deliver a load into a grain chuteor the like.

I do not limit myself to the particular mechanism shown for the reasonthat variations may be made therein without departing from the spirit ofmy invention.

I claim A device of the character described, comprising a vehicleprovided with wheels, scraper blades movable relatively to said wheels,rocking shafts connected with said scraper blades, a hand lever, a linkconnected therewith, a second lever connected with said link,connections from said second lever to said rocking shafts, and a pair oftensile springs connected with said second mentioned lever for holdingthe same in a predetermined normal position.
